Definitions

  • This invention is related to the manufacturing of the component named adapter plate, that is used in spring brake actuators, by means of composite, glass fiber reinforced plastic material instead of aluminium or steel material as in the known technique.
  • Adapter plate a component of spring brake actuators, is an auxiliary part that creates the service chamber when integrated with the upper housing part; and the park chamber when integrated with the lower housing part by means of a clamp or any formal connection.
  • spring brake actuators used in heavy commercial vehicles comprise of the service chamber that is operated under normal driving conditions and the park chamber that is activated in case of air leakage or discharge of the air deliberately (pulling the hand brake). If the vehicle is requested to be slowed down or stopped, the service chamber is actuated; and if the vehicle is requested to be fixed, the parking chamber is operated. In other words, the service chamber and the parking chamber function respectively when force is applied on the foot brake and on the hand brake.
  • Adapter plates are expected to withstand such forces without any breakdown during their working lives.
  • all of the adapter plates used are made of metallic materials such as aluminum or steel. Therefore, no problems are encountered with the adapter plates while carrying the loads. However except for these forces, there are also other important factors which affect the lifetime of the adapter plates. These are factors like corrosion and abrasion.
  • Adapter plate or other metallic components may be exposed to corrosion and disable the actuator particularly at sea costs or in humid areas.
  • This invention discloses an adapter plate that is made of glass fiber reinforced plastic material and fulfills all operation conditions of the spring brake actuators. This invention is related to the manufacturing of adapter plates by performing new designs and using glass fiber reinforced plastic material instead of aluminum or steel adapter plates used in conventional systems.
  • Adapter plates in existing systems are manufactured by sheet forming with hydraulic press or aluminum casting (sand mould casting technique, die casting, etc.).
  • the most serious disadvantage of all these methods is that the components require additional operations after casting or press forming like turning, welding or coating which takes time and adds cost. Hence, these components cannot be used in the product without these additional operations.
  • adapter plates can be used on the product immediately, without any additional operations.
  • Adapter plate works under high pressure conditions due to its working conditions. For this reason it has many sealing surfaces. In order to obtain high quality sealing, the surface treatment must be high quality. In steel and aluminum adapter plates the sealing problem is seen often.
  • the adapter plate manufactured by the conventional methods is the resistance to corrosion. Since the actuators are not mounted in a protected place on the vehicle, they are subjected to all kinds of air-borne effects. Hence, the adapter plates should be coated to ensure good resistance against corrosion.
  • the adapter plates made of metallic materials such as steel or aluminum are very heavy when compared to plastic. This causes both an increase in the transportation costs of the components and in the transportation costs of the brake actuators. Besides, on a vehicle its common to use more than two brake actuators and any reduction in weight will increase the load that the vehicle will carry according to law. This advantage in long term makes remarkable profit.
  • the composite adapter plate developed by this invention aims to
  • This invention is related to the manufacturing of the adapter plate used in the spring brake actuators and made of metallic materials such as steel or aluminum in the conventional systems by using glass fiber reinforced plastic material through the plastic injection method.
  • plastic material is used in this invention, it eliminates the problem of corrosion in the adapter plate. Therefore, it is not needed to carry out any process such as dying or coating the component.
  • Glass fiber reinforced plastic material used in the design is notably resistant against abrasion. With the use of the said design on the actuator, it does not necessitate the use of central designs (plastic additional components) mentioned in the US Patent No. 005829339A1.
  • FIG 1 and Figure 2 represent the perspective and sectional views of the conventional adapter plate (1) design.
  • feathers (3) are positioned at the periphery of the central section (2) of the conventional adapter plate (1) to increase the strength. These feathers (3) are designed to correspond the high forces created by the transfering of pressurized air to the service chamber (5) and parking chamber (6) through the air inlets (4) on the adapter plate (1).
  • FIG. 3 and Figure 4 represent the perspective and sectional views of the adapter plate (7) in the new design manufactured by the use of glass fiber reinforced plastic material.
  • the strength of the material disclosed in the invention (glass fiber reinforced plastic material) is low when compared to the strength of aluminum and steel. Therefore, larger feathers (8) are designed for the parking chamber (6) to correspond the exerted forces in the adapter plates for which the new material is used (7).
  • the said feathers (8) are capable of bearing all forces which the adapter plate (7) is exposed to.
  • the feathers (8) may be thicker and less in number; or thinner and more in number.
  • the feathers (8) may be designed in a different form. Large feathers (8) may have square, rectangular, circular, elliptic, rhomboid, trapezoid or curvilinear shape.
  • fittings are attached to the air inlets (4) of the adapter plates (1, 7) by means of screw threads. These fittings are required to remain attached in all road and air conditions. Thus, the said fittings are attached to the air inlets (4) by compressing with high torque.
  • Conventional adapter plates (1) made of aluminum or steel are able to resist against such high torque values.
  • the screw threads in the air inlets (4) of the adapter plates manufactured by the use of the new material, namely glass fiber reinforced plastic material (7) are not capable of resisting these torque values.
  • the parts which are made of aluminium or similar material and called insert (additional component) (9) are used in the air inlets (4) of the adapter plate (7). This further facilitates the compression of the fittings up to the determined torque values.
  • One of the parts that is exposed to the most abrasion is the central section (2) of the adapter plate on the actuator.
  • the parking brake force created in the parking chamber (6) of the actuator is transmitted to the service chamber (5) and the shaft by the central section (2).
  • sealing between two mentioned chambers (5, 6) is achieved by the said part.
  • Any abrasion which may occur in this part (2) may disable the actuator.
  • Glass fiber reinforced plastic materials are relatively resistant to abrasion. Thus, abrasions are avoided by the use of the adapter plate's (7) own material without further necessity for the use of additional component in the central section (2).
